morning gals
just come back from my first visit to dr ong.
quite happy with the decision to switch to him. He take time to explain things to us.. even through he has an operation to rush off to.
I ask him abt Down Syndrome test. Here's some info. that may be useful fo you.
At my age,30, the chances of having a SD kid is 1:800.
To evaluate the risk, I can take 1) NT test-scan 2) triple test-blood test
NT test has to be taken in the 11-14 wks and the accuracy is 70%
Triple test has to be taken in the 15-20 wk and the accuracy is 60%.
Result of 1+2 = 90% accurate...However, these 2 result only give Low/high risk..low risk does not = no risk.
If over 35, he advise to go straight to ammiv test, after 16 wk.. which is invasvise test and has a chance of miscarriage 0.5%(1:200) ~1% (1:100)... this test will give a confirmation( yes /no) result..
Anyway, ocscar means 1+2 ... because frm uk , where the term is taken, the 2 test are done together as the english only visit the gp/gynea twice throughout the preggy.
